A program for electron-impact broadening parameter calculations of ionized rare-earth element lines

In order to provide atomic data needed for astrophysical investigations, a set of electron-impact broadening parameters for ionized rare-earth element lines should be calculated. We are going to calculate the electron-impact broadening parameters for mark than 50 transitions:of ionized rare-earth elements; Taking into account that the spectra of these elements are very complex, for calculation we can use the-modified semiempirical approach - MSE or; simplified MSE. Also, we can estimate these parameters on the basis.of regularities and systematic trends.
